I looked in my guide and it contradicts itself.
13.1.2 intersections says pretty much nothing about shifting but a later paragraph called 13.1.11 gear usage, manual trans do not shift in intersections or turns.
I do not see anything about an auto???
I am still going to shift when it is time to shift!!! I do not haul hazmat anymore.
Now if you are a couple cars back you could catch 3 or 4 gears then go thru, it would be painful to get thru in low with a big load on a 5 lane intersection.
If the drivers did not shift with the big tankers and gravel trains in an intersection the backups would be long!
